An ergonomic filter synthesizer that you can use to create Finite Impulse Response (FIR) filters with custom coefficients and frequency response analysis tools #Filter synthesizer #Create filter #Filter analyzer #Filter #Synthesizer #Synth
WinFIR makes it as easy as possible to design Finite Impulse Response or, in short, FIR filters. Although designed with ease of use in mind, the application does feature an integrated code editor and frequency analysis tools that can help you in your attempts to design a filter.
Provided you are familiar with FIR filters and their limitations, working with WinFIR is easy. The one-window interface bundles all the features, without extra menus to get tangled in. The filter coefficients and the parameters in the lower side of the GUI determine the frequency and the impulse responses, as shown in the two graphs. Alternatively, you can load a configuration to perform frequency response analysis and optimize the filter. All data is stored in TXT files, which are easier to maintain.
WinFIR can generate low and high pass filters, as well as band pass and band stop filters. You are free to configure edge and sampling frequencies, as well as other parameters, such as the minimum attenuation and the maximum ripple.
The number of coefficients to deal with is also configurable and it can reach a maximum of 4095. WinFIR relies on the well-known "Parks-McClellan" algorithm to calculate them efficiently.
The impulse response, given by the filter coefficients, can be easily accessed via the integrated text editor, which also allows you to perform quick modifications to their values to see the effect they have on the frequency response.
The filter’s real performance can be analyzed by modifying the format of its coefficients. WinFIR supports 32 and 64-bit floats and integers.
WinFIR is designed for filter design, analysis and calculation, proving a reliable tool in filter synthesis. With its help, you can analyze the frequency and the impulse responses with visual support. And thanks to the integrated editor, it is easy to configure the filter coefficients.
